Benefits of technology
[0005]Some electronic devices are incorporated with a scrolling key to execute the scrolling function, which occupies more space and increases costs thereof.
Problems solved by technology
Electronic devices with a display screen, such as handheld devices, cannot display a whole image due to limited size of the display screen.
However, this method is slow and inefficient.
Some electronic devices are incorporated with a scrolling key to execute the scrolling function, which occupies more space and increases costs thereof.

Embodiment Construction
[0009]FIG. 1 is a schematic diagram of one embodiment of an electronic device 10 as disclosed. In one embodiment, the electronic device 10 may be a mobile phone, a personal digital assistant, or a portable computer. The electronic device 10 includes a keypad 100, a detection module 110, a timer 120, a comparison module 130, a storage module 140, a user interface module 150, and a display screen 160. The keypad 100 includes a plurality of keys to receive key inputs from a user. An example of the keypad 100 is shown in FIG. 2, including twelve keys. In this embodiment, the key inputs indicate an operation from the user on the plurality of keys of the keypad 100, including a press and / or a sliding input. The user interface module 150 controls the display screen 160 to display an image. The electronic device 10 detects sliding operations of different directions on the keypad 100 to control the image scrolling correspondingly. It may be understood that the keypad 100 in FIG. 2 is exempla...

An electronic device includes a keypad including a plurality of keys, a display screen, a user interface module, a storage module, a detection module, a timer, and a comparison module. The storage module stores a scrolling key input interval, and a plurality of predetermined key sequences and corresponding scrolling events. The detection module detects and temporarily stores key inputs. The timer times intervals between neighboring key inputs. The comparison module determines if the intervals between the neighboring key inputs exceed the scrolling key input interval and if the key inputs match with one of the plurality of predetermined key sequences. The user interface module scrolls a current image according to a scrolling event from the comparison module and controls the display screen to display the scrolled image.
Description
BACKGROUND[0001]1. Technical Field[0002]The disclosure relates to electronic devices, and particularly to an electronic device with a keypad and a screen and display controlling method.[0003]2. Description of Related Art[0004]Electronic devices with a display screen, such as handheld devices, cannot display a whole image due to limited size of the display screen. Thus, scrolling through the image is needed to view the whole image. In order to scroll through the image, a key must be pressed for many seconds to trigger a scrolling function. However, this method is slow and inefficient.[0005]Some electronic devices are incorporated with a scrolling key to execute the scrolling function, which occupies more space and increases costs thereof.BRIEF DESCRIPTION OF THE DRAWINGS[0006]FIG. 1 is a schematic diagram of one embodiment of an electronic device as disclosed.[0007]FIG. 2 is a schematic diagram of a keypad of the electronic device of FIG. 1.[0008]FIG. 3 is a flowchart illustrating a ...
